Folding Prop Recommendation for SD50 Saildrive?

I have two Yanmar 4JH4CE engines with SD50 saildrives. They came with fixed props. I am interested in switching them out for folding props and would like to hear any recommendations and experiences with same. Thanks

My opinion on flolding props is pretty low when it comes to using them on anything other than a raceboat. They are generally a compromise in powering and with extended use (ie on a cruising boat) they wear and begin to rattle and cause vibration. Better choice would be a well made feathering prop. Not quite as big of a reduction in drag but they retain all (or at least nearly all) of the perfomance when motoring of a fixed prop and many outperform in reverse when it comes to prop walk. That being said they are also significantly more expensive. I have used folding props on race boats and they are the way to go but no one intends to do any significant motoring or motorsailing like when trying to claw off a lee shore in heavy weather with a race boat.

gbanker,

On a cat with saildrives. Folding props are the only way to go.
Lets you motor better with just one engine.
